Fig. 13 is a view similar to Fig. 3, illustrating a modification, and

Figs. 14, 15 and 16 are detail views of the form shown in Fig. 13.

The frame of the machine is similar to that of an ordinary standardtypewriter and comprises a base portion 10, corner uprights ablecarriage 13 is mounted in suitable guides Fig. 1 is a vertical sectionfrom front to 11 and a top plate 12. A transversely movat the upper rearportion of the frame and carries a cylindrical paper platen 14. The typebars 15 are carried'by suitable hangers on a segment 16 and arepivotally mounted in front of and below the platen and are arranged toswing upwardly and rearwardly and strike. the front of the platen.Upright sub-levers 17 arranged in rearof the segment are connected attheir upper, ends to the individual type bars by links 18. The sublevers.17 are pivoted adjacent their lower ends upon a transverse rod 19and'the extreme lower ends of the sub-levers are provided with pivotpins engaged by. slots formed in the forward ends of a series of code oractuating bars 20. Individual springs 21 connected to the forward endsof the code bars hold the latter and the type bars in normal positionand tend to move the rear ends of the code bars upwardly into engageoffive selector or permutation bars 22.

The selector bars 22 extend transversely of the machine through guideslots formed in the lower portion of a bracket 23. Lugs 24 (see Fig. 3)limit the movement of the selector bars and spring pawls 25 hold them inadvanced or retracted positions.

The selector bars are adapted to be positioned as usual in differentcombinations and are so notched that in any settin one of the code barscan rise into the note es thereof. The rear ends of the code bars arenormally held depressed by a transverse bail or drop bar 26 and eachcode bar has a shoulder 27 which, when the code bar is selected, extendsinto the path of movement of a striking bail 28. The bails 26 and 28 aremounted res ectively on transverse pivot shafts 29 an 30 mounted in endbrackets 31 and are connected by adjustable operating links 32 to, arms33 and 34 which are mounted on a transverse arms. 34 and 33 and thestriking and'drop bails 28 and 26. Springs 40 and 40' (see Fi 2)connected to the bails 28 and 26 hold rollers on the arms 33 and 34 inengagement respectively with the cams 39 and 37 and the latter areprovided with abrupt shoulders which, as they pass beneath the rollerson the arms, permit the springs to successively actuate the ails so thatthe selected code bar is lifted by its spring and then thrust forwardlyby the striking ail. Preferably as indicated in dotted lines in Fig. 1,the striking bail swings on an arc having a short radius so that it isdisengaged from the shoulder 27 of the selected code bar slightly beforethe corresponding type reaches the printing point, the continuedmovement of the type being effected by the momentum of the moving parts.In this way a uniform action is imparted to the type bars and the latterare free to quickly rebound from the printing point.

The arm 3 which operates the striking bail is forked and has one roller41 which cooperates with the cam 39 as described. It also has a secondroller 42 on the opposite side of the main shaft whichlis arranged to beengaged by the cam lug 38 after the roller 41 as passed the shoulder ofthecam 39 so that, if the spring 40 of the bail fails to effect itsoperating movement, such movement will be positively effected by the cam38. With this arrangement the bail 28 is sprin -actuated to effectoperation of the type bars ut its operation is positively insured sothat it can be employed also for operating the function mechanismswhich, for the most part, re uire more power. Since the striker bar orball 28 is thus positively operated, if necessary, to insure theactuation of the function mechanisms, the spring, which effects the t ebar operating movement of the bail, can e li ht and quick acting andneed not be placed un er excessive tension.

The settin of the selector bars is controlled by a set of ve selectorsorplun ers 43 horizontall movable in line with t e left-hand ends 0 theselector bars which, as shown in Fig. 6, are preferably offset to alignwith suitable o nings in a supporting plate 47 at the side 0 the machineame, and the pins 44 extend through notches 48 in a fixed cam ring 49mounted on the inner face of the plate.

The selector actuator is connected to rotate with the shaft but isaxially movable thereon. It comprises a cylindrical shuttle 50 keyed toa sleeve 51 which is adjustably connected to the shaft by a screw 52. Ahorizontal pin 53' fixed to the shoulder extends through an opening in aflange 54 on the sleeve and a spring 55 coiled about the pin holds aroller 56 on the shuttle in engagement with the cam ring 49. To reducerolling friction the roller and cam ring are provided with conicalcontacting faces. As the shaft and shuttle rotate the roller is forcedintothe notches of the cam ring by the spring 55 and thereby engage thepins 44'to advance the selecting plungers 43. The inner ends of thelatter extend throu h a guide plate 57 and lugs 58 connected t9 t eplungers are fixed to guide pins'59 which also extend through the plate57. Spring pawls 60' engage the pointed lower ends of the lugs 58 andhold the selecting plungerseither in. advanced or retracted posltions.

The receiver is operated in response to line signals of unifprm lengthand comprising permutations of two different line conditions extendingthrough five intervals or units. In addition with the preferred formshown each signal is preceded by a uniformstarting line condition andthe line is re stored to normal for at least a definite interval at theend ofeach signal. 1

When the selecting plungers are advanced the upper ends of the lugs 58engage a cam 'disk 61 which is fixed to a sleeve 62 on the main shaft36. At one point thecdisk 61 is provided with oppositely inclined camlugs 63 and 64 which are arranged-to engage the beveled edges of thelugs 58. .A second cam disk 65 is fixed to the sleeve 62 provided with acam lug 66 which is arranged to cooperate with the beveled edges of aseriesof upwardly projecting lugs 67 on the adjacent ends of theselecting bars 22. The cams move in the direction indicated by the arrowin Fig. 6 and are arranged so that the cams 66, 63 and 64 actsuccessively to restore any advanced selecting bars, transfer thesetting of the se- 'lectors 43 to the bars and restore the selectors forfurther operation, the arrangement being such that the selector bars arethus set before the bails 26 and 28 are operated to actuate the selectedcode bar and the selectors can be again-positioned before the printingof the pi'ecedding character selected thereby is comp ete The operationof the main shaft 36 and of the selector actuator 50 is controlled byelectro-magnetic means in response to the-line impulses. The shaft isdriven from a motor clutch. As shown, the motor shaft 68 is providedwith aworm 69 which engages a worm wheel 70 which is fixed to aconstantly driven clutch member 71. The latter is loosely mounted on thereduced outer end of the shaft 36 and cooperates with a driven clutchmember 72 connected to the shaft. A sleeve 73 fixed to the shaft isprovided with notches which receive lugs 74 on the clutch member 120through suitable gearing anda start and stop 72 so thatthe latter willslide axially to engage and disengage the driven clutch member 71.Preferably, as shown, the engaged faces of the clutch member areprovided with cooperating teeth. A spring 75 extending be: tween aflange of the sleeve 7 3 and the clutch member 72 tends to move thelatter to close .the clutch but the clutch is normally held open by apivoted trip 76 which is arranged to engage a lug 77 on the clutchmember 72, the lever and lug having cooperating inclined faces which asthey are engaged cam the downturned inner end .of the armature 80 isarranged to engage the outer reduced end of the shuttle when the magnetis deenergized, and, if the magnet is thus deenergized when the shuttleroller passes through one of the notches of the cam ring 48, theselector actuating movementof the shuttle is arrested and thecorresponding selector plunger remains in retracted position. But if themagnet is energized as the roller moves into register with one of thenotches 48, the roller will be forced into the notch by the spring andwill operate the corresponding plungor as previously described. Theshaft 36 is driven in substantial synchronism with the received signalsso that the roller 56 registers with the notches 48 of the cam ringduring the mid portions of the five selecting intervals or units of thesignals,- and the selectors are thus variably set in difierentcombinations in accordance with the different signals.

The trip lever 76 is provided with an end portion which projects withinan internal cam 83 on the shaft 36 (see Figs 3 and 4). During thesetting of the selectors by the conjoint operation of the rotaryactuator and .magnet 81 the trip lever holds the latch 79 out of thepath of movement of the armature 80'. But near the end of a revolutionof the shaft :1 lug 83' on the internal surface of cam 83 engages theend of the lever and returns it to normal position in engagement withthe latch 79 and, at the end of the revolution, the trip leverdisengages the clutch member 72 and arrests the main shaft 36 in normalor zero position.

Preferably the circuit of the magnet 81 which responds to all lineimpulses is nor mally closed and the uniform starting inter val of eachsignal opens its circuit. Thereafter its circuit is variably opened andclosed during the selecting intervals of the signal and again closedduring the uniform spacing interval at the end of each signal and duringwhich interval the clutch is opened and the shaft 36 arrested. Theselector mechanism and printer are thus stopped at the end of eachsignal and again started in phase with the receiving signals by uniformstarting intervals which accompany all signals. It should be noted thatat each revolution of the shaft one character is selected and'the pre-vviously selected characteris printed.

The selector mechanism shown in Figs. 13, I4 and 15 is adapted to becontrolled by a rotary distributor which is provided with suitable meansfor maintaining it in synchronism with the received signals. Theselector bars, main shaft and controlling clutch are similar inconstruction to the corresponding parts already described, but theclutch instead of being tripped by the starting interval of the linesignals is controlled by the usual sixth. pulse magnet 84 which directlyopera-tes the pivoted clutch trip lever 85. The selectors are in theform of pivoted bell cranks 86 which are adapted tobe advancedby springs87 but are normally held retracted by pivoted spring held latches 88.The latter are tripped b-y-plungers 89 operated by the armatures 90 ofthe set of five selecting magnets 91 to which the signal impulses aredistributed. The selectors 86 are provided with plugs 92'which arearranged to be engaged by the setting and restoring lugs 63 and 64 ofdisks 61 and which, as already described, serve to transfer the settingof the selectors to the selector bars and restore the selectors forfurther operation during the printing of the preceding characterselected thereby. A pivoted lockout member 93 extends beneath one end ofthe trip lever 85 and nor- (see Figs. 1, 7 and 8) and comprise a ratchetwheel 94 connected to the rear end of shaft 95, the forward end of whichis provided with a pinion 96 meshing with a rack 97 on the rack. Shaftis Journaled in a bracket 95 on the upper rear portion of the frame. Adepending portion of the bracket guides a veuticaly movable dog holder98 which carries a pivoted, spring-held space dog arranged to engage theratchet 94. The latter-is also engaged by a spring held holdingeffected'by a pawl and ratchet mechanism dog 100. The lower end of thedo holder v 98 is adaptedto be engaged by an a justable abutment onv therear end of an arm 101that.

that during the first half of the revolution of shaft 36, the feedingdog 99 is held substanstially in its normal position and 1s then loweredto engage the next tooth of the ratchet wheel 94. During the second halfof the revolution of the shaft, the dog is raised to move the ratchetwheel and advance the carriage one step. At the end of the revolution,as stated, the roller drop-s into notch 105 of the cam and acts as adetent to hold the shaft 36 against accidental movement. Also when thisoccurs the feeding dog moves from the tooth of the ratchet 94 and thecarriage return spring will hold the carriage in position with a toothof the ratchet engaging the holding dog 100.

A number of code bars, preferably five, are provided for selectingcertain functions, namely, case shift and release, line space, carriagereturn and signal. The line space and carriage return code bars 20 and20 are connected to the lower ends of upright sublevers 17 and 17 (seeFigs. 8, 9 and 12). The lever 17 is arranged to oscillate a lever 106which is adapted to operate a spring held bail 107 mounted on the'shaftof the carriage platen. Asuitable spacing dog 108 on the bail isarranged to engage a ratchet wheel 109 fixed to the platen.

The lever 17 b is connected at its upper end by a link 110 to a bellcrank 110 and the latter is connected by a link 111 to a cam 112 looselymounted on the shaft 95. This cam is arranged to engage pins 113 on thespacing and holding do s 99 and 100 and thereby these dogs aredisengaged from the ratchet 94 to permit the usual carriage spring toreturn the carriage. Notches-for the pins in the edge of the cam holdthe dogs disengaged until the carriage return movement, is completed.When this occurs a lug 114 on the carriage strikes a corresponding lug115 on the'cam 112 and restores ilt and the spacing and holding dogs tonormal.

The three remaining function code bars 20, 20 and 20 are pivoted attheir forward ends to a series of short pivoted levers 116, which arespring-held in position and are connected to their respective code barsby springs which tend to move such code bars upwardly into engagementwith the selector bars 22. One of the levers 116 has an extension on itslower end which is connected at its lower end by a link 117 to a bellcrank 118, and the latter is connected by a link 119 to a crank arm 120on a rock shaft 121. Another end engages and releases the locking dog123 and the type bar segment is restored to normal position for printingletters. Code bar 20 is arranged to operate an audible-signal of anysuitable type. This codebar and one ofthe character code bars 20 arearranged on opposite sides of the case shift code bar 20, and the rearends of these code bars are provided with depending stop lugs 123, 124,and 125 so arranged that normally the stop 124 on the shift code bar isabove the lug 123 on J the signal code bar, but when the case shift isoperated and locked in shifted position the stop 124 is above the lug125 on the character code bar 20. Selecting bars 22 are sonotched thatin a single setting in response to one combination both the code bars 20and 20 are selected but only one will be operated in accordance with thecondition of the case shift mechanism. Normally the character code bar20 will be operated in response to this combination, but if the shift isin operated condition the signal code bar20 will be operated. I

The rear ends of the code bars-extend through guiding slots in a combbar 126 on the bracket 23. A plate or bar 127 is mounted on the rearface of the comb bar by means of pins 128 which extend through inclinedslots in the plate. The latter at one end has a depending portion 129which is arranged to be engaged by any one of the function code barswhen operated so that the plate is thereby lifted, as indicated indotted lines in Figs. 7 and 8. lVhe-n so lifted a lug 130 on the innerend of the bar 127 extends into the path of movement of a lug 131 on thearm 101, and the latter and the spacing dog are not moved sufficientlyto affect the letter spacing operation when the shaft 36 and cam 102 arerotated. When the roller 104 011 the arm 101 drops into the notch 105 atthe end of the rotation of shaft 36 the lug 131 holds the plate or bar127 in raised position, but, at the next operation as the roller ridesout of the notch the bar 127 is released and drops back to normal. Thespacing mechanism alone can be operated by a special signal which doesnot select any of the code. bars.

It should be noted that all the parts, in cluding the operating cams,are, shown in their normal or zero position in the drawings. Theactuator is brought to rest with its roller on the extended raisedportion of the cam ring 49 between the first and fifth selectoractuating pins al v and which space corresponds to the starting andspacing intervals of the line signals. B rotatively adjusting the sleeve51 on the shaft 36, the zero position of the actuator can bevaried totake care of the lag of the receiver starting means so that the shuttleroller will register withthe first selec-ting pin during the mid portionof the first selecting interval of the line signals.

Numerous changes may be niadein the details set forth without departingfrom the essentials of the invention as defined by the claims.
